Application ie'dnarcii s, 1926. "sei-mino. 933133@ y I i'ovide ra simple ine'Xcnsive, but effective device for 'rapidly making bands of the above-described character.'

A' 'particular object of the to provide, in combination, power driven pressure rollers and a supportfor guiding a strip o'f lmaterial therebetween, and on ivhichthe'stiip may be spliced o`r additional plies applied to form theba'nd, and'ofmeans for inovinethe 'lower roller forwardl f adjacent the rear edge ofthe support to facilitate threading of a strip of material about the support'and the lower V"rollerand also to facilitate removing `of a 'completed band. The foregoing and other Iobjects arcobtain'ed by the 'apparatus illustrated in the accompanying ydrawings and described 'beloW..v It is to 4be understood .thatfthe invention is not limited to the specific 4for-m thereof, ShWIl and described herein.V i 1 O'f the accompanying drawings:

is provided to normally hold roller 151 in kContact with roller V10, 'spring' 19 being Connectedto the base 15- of'standard 15 and to a lug'20 connected to bracket 17. Itorinoving roller 11` forwardly away `from 1roller 10, .af hand lever 21 is' vconnected lto bracket 17 :for rocliing'tlie saine. "Spring 19 is so arranged as to contacta port-ion lof bracket 17'ixvhen the latter is'rocked forwardly to A' permit ,the Weightof the Vroller *11* and arms 16 to overcome the springl and thus beheldl in its forward position until 'man- Y ually moved rearivardlyxby .lever 21.

defsirablelto`-maintain the loop in the band y beloivthetable 24 and `rollers l'Oa'nd 11 `in taut condition. Accordingly a roller 28 is journaledbnra rod 29 vsecured so Vas vto be parallel to rollers 10, rllandlQ yOna-collar 8O ivlii'chis vertically adjustable on standard 15 that the 'machine' may bevused for lniilding bandsl of vai'ious'sizes. Collar 30 may vvbe secured in adjustedV positions on standard 15 by anysuitable form of clampV VDriving of the device is accomplished e means of a motor 32 secured on standardl" 'i and having arpulley 33 thereon for driving abelt 34 trained over a pulley 35 secured on l a shaft 36. Shaft 36 is journaled' in standard l and has a pinion 37 thereon meshing f witha gear 38 on roller l0. Roller 1,1 has a. gea-r 39 thereon adapted to `mesh with-'gear y38 when it is in cooperation with roller l0.

Belt 3-l is arranged YnormallyY to slip so as lnot'to drive rollers l0 and l1. In order to tighten upV said belt atvwill to driverrollers l0 and 1l., a

moved against the outer side of one reach `of belt 34, pulley 4Q being journaled on one arm of a bellwranlr` lever 4lv rookable on Y standard l5. A rod l2 is provided to rook lever 4l being Connected tothe other arm thereof and to a pedallever 43 fulerumed at all, The lever 43 has a weight 45v thereon "normally urging pulley 4() away from belt341. L y Y In use, the parts will be operated to the positions shown inFigure l. A fabric strip 'S of proper width and lengtlrfor forming the band is threaded Abetween rollers l0 and ll and about 'rollers 28 and 26 and its ends are spliced on table 24. Lever 2l is then swung rearwardly and pedal ll3pdepres`sed,V Vwhereby the band will be driveny along a substantially triangularv path. Additional pliesindioated at P., Figure 2, may be added as desired, theleading end of eaelrply being applied to the band on table 24: and the plies being progressively rolled into intimate eongl tact as will be understood. l v

Afterthe band is completed,y pedal 43 is released and hand leverQl is swung'forwardly, thus permitting easy removal of the Vbandfrom about rollers 1l, 28 and26 and table 24 to the left as shown in Figure 3.
